Versions Compared

Key

  • This line was added.
  • This line was removed.
  • Formatting was changed.

...

  • Set and Revert Log Levels: Temporarily change the log level and revert after a specified duration.

  • Flexible JSON Parsing: Uses jq for JSON parsing if available; defaults to jq otherwise.

  • Detachable Session Execution: Runs in a detachable session using screen or tmux, allowing the script to continue running independently of the terminal session. If both screen and tmux are installed, the script will prioritize screen first.

  • Supports Cluster and Node Log Levels: Allows setting log level at both the cluster and individual node levels.

  • Log File Auto-Detection: Automatically detects and adjust the castor.log file path for CSN and SCS environments.

  • Log Size Monitoring: Reports the log size generated during the temporary log level change.

  • Countdown Display: Shows a countdown for the specified duration.

...

  • jq: Used for parsing JSON responses; falls back to grep if unavailable.

  • screen or tmux (optional): Required for background execution.

  • Permissions: Ensure sufficient permissions to execute on the DataCore Swarm server and access required files.

Script Usage

Handling Passwords with Special Characters

If your password contains special characters such as @, #, $, & or !, you need to properly escape them or enclose the password in single quote (') when passing it as a parameter. Alternatively, use a secure password prompt.

Example 1: Escape special characters in the password

Code Block
./castor-change-log-level.sh -d <node_ip>192.168.8.84 -p <admin:password> [-i new_log_level | -L new_node_log_level] [-t <duration_in_seconds>] [-D --detach] [-v]

...

Parameter

...

Description

...

-d, --swarm_ip

...

IP address of the Swarm API endpoint (or set SCSP_HOST environment variable).

...

-p, --credentials

...

Admin credentials in the format admin:password. Secure password entry is prompted if not provided.

...

-i, --log.level

...

admin:pa\@ss\$word -i 20 -t 600

Example 2: Enclose the password in single quotes

Code Block
./castor-change-log-level.sh -d 192.168.8.84 -p 'admin:pa@ss$word' -i 20 -t 600

Example 3: Use the secure password prompt (Recommended)

Code Block
./castor-change-log-level.sh -p admin -d 192.168.8.84 -i 10 -t 300

The script will securely prompt you to enter the password without exposing it in the command line.

Usage of the script as described below:

Code Block
./castor-change-log-level.sh -d <node_ip> -p '<admin:password>' [-i new_log_level | -L new_node_log_level] [-t <duration_in_seconds>] [-D --detach] [-v]

Parameter

Description

-d, --swarm_ip

IP address of the Swarm API endpoint (or set SCSP_HOST environment variable).

-p, --credentials

Admin credentials in the format admin:password. Secure password entry is prompted if not provided.

-i, --log.level

New log level to set (values: 5, 10, 15, 20, 30, 40, 50, chatter, debug, announce, info, error, critical, default).

-L --node.log.level

New node log level to set (values: 0, 5, 10, 15, 20, 30, 40, 50, chatter, debug, announce, info, error, critical, default).

-t, --time

Duration in seconds to keep the new log level (optional).

-D, --detach

Runs the script in a detachable session using screen or tmux, allowing continued operation if terminal session ends (optional).

Instruction for Use

Example 1: Set cluster log level to 20 and keep it for 10 minutes

...

Code Block
./castor-change-log-level.sh -d 192.168.8.84 -p admin:datacore -i 20 -t 30 -D

Running the Script at a Specific Time

The at command can used to schedule the script to run at a later time. This is useful when you need to start collecting debug logs at a specific hour.

Example 4: Secure password prompt if password are not providedExample 4: Secure password prompt if password are not provided

Code Block
./castor-change-log-level.sh -p admin -d 192.168.8.84 -i 10 -t 300

You will be prompted to enter the password securely.

Code Block
./castor-change-log-level.sh -p admin -d 192.168.8.84 -i 10 -t 300

...



Enter password for user admin:

Running the Script at a Specific Time

The at command can used to schedule the script to run at a later time. This is useful when you need to start collecting debug logs at a specific hour.

Example 5: Schedule the script to run at 3:00 AM on 03/02/2025 and collect debug logs of node 192.168.8.84 and 192.168.8.89 for 1 hour

  1. Ensure the at service is installed, enabled and running

    Code Block
    dnf -y install epel-release
    dnf -y install at
    systemctl enable --now at
  2. Schedule the script execution using at:

    Code Block
    echo "/root/dist/castor-change-log-level.sh -p admin:datacore -d 192.168.8.84 -L '192.168.8.84,192.168.8.89' 10 -t 3600" | at 03:00 AM 03/02/2025

...

  1. To verify scheduled job:

    Code Block
    atq
    7	Sun Mar 02 03:00:00 2025 a root
  2. To remove a scheduled job (replace JOB_ID with the actual job number from atq output):

    Code Block
    atrm 7

Behavior

  1. Log Level Change: Sets the log level to the specified value. If the current log level matches the requested level, the script skips the update.

  2. Countdown: During the specified duration, the script displays a countdown every second.

  3. Revert Log Level: After the countdown, the log level reverts to the initial value.

  4. Log Size Report: Provides approximately log size generated during the temporary log level change.

Reattaching to a Detached Session

For more details on using screen and tmux, refer to their official documentation:

If you accidentally close your terminal (e.g. putty, iterm2, etc) while the script is running in a detached session, you can reattach using the following commands:

For screen users:

  1. List active screen session:

    Code Block
    screen -ls
  2. Reattach to the session:

    Code Block
    screen -r <session_name>

For tmux users:

  1. List active tmux sessions:

    Code Block
    tmux ls
  2. Reattach to the session:

    Code Block
    tmux a -t <session_name>

If the session has ended or was not found, you may need to restart the script manually.

  • Connection Issues: If unable to connect to the Swarm API, check the IP, credentials, and network access.

Reattaching to a Detached Session

If you accidentally close your terminal (e.g. putty, iterm2, etc) while the script is running in a detached session, you can reattach using the following commands:

For screen users:

  1. List active screen session:

    Code Block
    screen -ls
  2. Reattach to the session:

    Code Block
    screen -r <session_name>

For tmux users:

  1. List active tmux sessions:

    Code Block
    tmux ls
  2. Reattach to the session:

    Code Block
    tmux a -t <session_name>

If the session has ended or was not found, you may need to restart the script manually.
